ISF filing (Importer Security Filing 10+2)
For ocean imports, the Importer Security Filing (ISF, or 10+2) must be filed before your cargo loads at origin. Niel Customs prepares ISF for timely filing by a licensed customs broker, who is responsible for the filing.
Ready before your cargo loads
ISF must be submitted to CBP at least 24 hours before ocean cargo is laden at the foreign port. We track the deadline so the filing is prepared on time.
The 10 importer data elements
ISF requires ten data elements from the importer (plus two from the carrier). The platform helps gather and validate them from your shipping documents.
Avoid ISF penalties and holds
Late or inaccurate ISF filings can lead to CBP penalties and cargo holds. Timely, broker-reviewed filing keeps your cargo moving.
Connected to your entry
ISF is prepared as part of the same case as your customs entry, so the data stays consistent from security filing through to release.
